Abstract: A method for injecting a treating liquid into a wood or stone material.  The liquid is injected in an initial pressure-applying/injecting step in which the wood or stone material is immersed at ambient temperature in a treating liquid under an initial liquid pressure of 1 to 10 kg/cm2, and maintained at this pressure for a period of time. Subsequently, the pressure is increased to a final pressure having a maximum value of 50 kg/cm2.  Where wood is being treated, the pressure is raised in a plurality of steps of 5 to 10 kg/cm2 each, followed by a defined holding period.  Where stone is being treated, the pressure is increased in a single step.  Finally, the treated material is depressurized over a period of at least 20 minutes.

Abstract: A method of making an elongate plastic member assembly (76, 80, 84, 88) includes providing at least an elongate plastic member (62) having a plastic wall (66). One portion of as elongate plastic member (62) is aligned adjacent to another portion of an elongate plastic member (62) and the walls (66) of the adjacent elongate plastic members are plasticized. The plasticized portions of the walls are flowed into a mold (32) between adjacent elongate portions to fuse the adjacent portions together. A peelable elongate plastic member (76, 80, 84, 88) is made is accordance with the process described above. The elongate plastic member assembly may be made of a single elongate plastic member (62) in a coiled configuration or a plurality of elongate plastic members joined in parallel at selected points along their length. Another aspect of the present invention is an apparatus (10) for making an elongate plastic member assembly. The apparatus (10) includes complementary upper (14) and lower (16) radio frequency dies, each die having a leading surface (20', 20) with a plurality of parallel grooves (22', 22) therein including a first and a last parallel groove. Adjacent parallel grooves of both dies are separated by a land strip (28', 28) of the leading surface. An outermost edge of the first and last parallel grooves of at least one of the upper and lower dies is beveled (34, 36, 38, 40). Parallel grooves of the upper and lower dies, with the leading surfaces in an operative position, define a plurality of receiving channels (30) and the land strips define a plurality of flow chambers (32). A press (60) is provided for bringing leading surfaces of the upper and lower dies into an operative position in close proximity to one another. A radio frequency generator (18) selectively applies as energy potential between the upper and lower dies to plasticize the elongate plastic members, whereby plastic flows into the flow chambers (32) to fuse adjacent elongate plastic members together.

Granted: 2000-10-31
Abstract: A disc filter assembly includes a number of filter discs mounted in a vat by a horizontal shaft with an inter-disc volume between the discs. A feed mechanism is provided that makes it possible to feed the pulp suspension onto the surface of the liquid, directed toward the most concentrated pulp in the vat, in such a manner that the feed is insensitive to fluctuations of the suspension surface level in the vat. This is accomplished by feeding the suspension into the vat interior directly into each of the inter-disc volumes, as by using a chute (which may have the approximate configuration of a hollow triangular parallelepiped) for each volume. A header for supplying pulp suspension to the chutes may be mounted on or spaced from the sidewall of the vat, or above the vat.

Abstract: A process for upgrading a low rank coal and a heavy oil to produce an improved coal product and an improved oil product. First, the low rank coal is dewatered to reduce its moisture content to less than about 4 percent in order to render the low rank coal more oleophilic. Next, the dewatered low rank coal is mixed with a quantity of the heavy oil of between about 15 and 40 percent of the dry weight of the low rank coal so that the heavy oil substantially contacts the low rank coal in order to produce a mixture. The mixture is then heated to a temperature less than the mild thermal cracking limit of the mixture in order to separate hydrocarbons from the mixture and to produce the improved coal product. The hydrocarbons separated from the mixture during the heating step are then collected in order to produce the improved oil product.
